Well, I should be sittin' in an air conditioned office in a swivel chair Talkin' some trash to the secretaries, Sayin', "Here, now mam-ma, come on over here."Instead, I'm stuck here rubbin' these udders with a rag And walkin' home in smelly old shoes With them steadily depressin', low down mind messin' Workin' at the cow wash blues.

Cornel University did a study on dairy cows that used mechanical brushes. Their results showed less mastitis and higher milk output for those that used the brush compared to those that did not have access to the brush.

Also, these dairy cattle aren't what you want your steak to come from. These are what you will see later in your cheeseburgers.
